How to fix or mitigate CVE-2026-65896?

Within 24 hours, immediately audit all users holding api.pages.write permissions and restrict access to essential personnel; simultaneously review API plugin logs for suspicious directory move operations at the /pages/{route}/move endpoint. Within 7 days, upgrade the Grav API Plugin to version 1.0.10 or later across all deployments. Within 30 days, audit page directory structure for unauthorized out-of-scope relocations and implement continuous monitoring for suspicious API activity.

HIGH 7.1

DescriptionCVE.org

Grav API Plugin (Composer package getgrav/grav-plugin-api) before 1.0.10 fails to properly validate the slug field in the POST /pages/{route}/move endpoint. PagesController::move() sanitizes the slug only with ltrim($body['slug'], '.'), which strips leading periods but does not neutralize '/' or '..' segments. An authenticated API caller with the api.pages.write permission can supply path traversal sequences (e.g., 01.home/../../../pwned) to move an entire page directory (content and media) to an arbitrary writable location outside user/pages/, including outside the Grav installation.

AnalysisAI

Path traversal in the Grav API Plugin (getgrav/grav-plugin-api) before 1.0.10 lets an authenticated caller holding the api.pages.write permission relocate an entire page directory outside user/pages/ and even outside the Grav installation. The flaw sits in the POST /pages/{route}/move endpoint, where PagesController::move() only strips leading periods from the slug and never neutralizes '/' or '..' segments. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but an upstream fix and a GHSA advisory are published.
